[QUOTE="plynn41, post: 1398782, member: 107560"] No one can answer the question about how much to mill the head without measuring the current squish clearance, which can vary quite a bit on a stock engine because of machining tolerances. Your squish band clearance ought to be somewhere between 1.0 and 1.4 mm for optimal performance. If you mill the head and set the squish band where you want it, it could increase your octane requirements, but most likely it won't be a radical change. And sometimes the engine will run better on the same gas because the combustion chamber will be more efficient.. And Dave is right, you'll feel the difference in the bottom end. [/QUOTE]
